Replace selected identifiers consistently or redact sensitive columns. Consistent pseudonyms preserve equality within selected columns; they are not irreversible anonymization. Linkability and unselected fields can still identify people. A supplied secret salt + SHA-256 is deterministic pseudonymization, not an encryption key vault. No automatic PII discovery or compliance certification. Mapping secrets are not included in result exports.

Prepare the input

Replace selected identifiers consistently or redact sensitive columns.

CSV, TSV and arrays of scalar JSON objects are supported. Identifiers stay text. Empty cells are missing by default; add special missing tokens only if their meaning is certain. Use the sample to inspect the exact workflow.

Keep the useful output

Review the summary and result records. Transformation tools retain separate change, rejected-record or diagnostics datasets where relevant. Choose the dataset before exporting; a report and a cleaned dataset serve different purposes.

CSV exports protect formula-like text. JSON keeps data portable without making an Excel workbook. Reports and editable backups may contain private source values; download only what you intend to share. No automatic account storage or server processing is used.
